Ogres.

The dwarves' defenses would crumble if the giants were to scale the walls. The cauldrons of molten slag were empty, the cache of stones depleted. For a moment Glandallin's doubts returned, but a glance at Giselbert's gleaming figure assured him that evil would be defeated in the time-honored way.

The mass of orcs stirred and a cheer went up as the ogres approached.

Marching to the head of the army, the enormous beasts, uglier and more oafish than even the orcs, deposited their grappling irons, the four prongs of which were the length of a fully grown man. They attached long chains to the stem of each hook.

The apparatus is ill suited to climbing, thought Glandallin. The beasts intend to topple the walls.

Whistling through the air, three dozen claws buried themselves in the stonework. A shouted order summoned the watching orcs to join the ogres in their tug-of-war. A crack of whips sounded and the jangling links pulled taut.

Glandallin heard the wall groan softly. The stronghold, built many cycles ago by his kinsmen, was no match for the beasts' raw power.

"Quick, bring the wounded to safety!" he bellowed.

The party of dwarves responsible for tending the cauldrons left their stations and carried off Glamdolin and the other ailing warriors.

Masonry crumbled as a section of crenellated battlement ripped from the wall. The grappling hook went into free fall amid the showering stonework, killing two ogres and ten orcs. The enemy forces held their ground. Soon the hook was ripping through the air again, poised to sink its claws into the wall.

This time the dwarves retreated, abandoning the parapet just in time. They took up position in the barbican above the gates.

Glandallin listened as a large section of wall crashed and shattered on the ground below. The earth quaked and the invading army howled in triumph.

Good luck to them, thought Glandallin, endeavoring to stay calm. I hope they dash their brains out on the doors. The gateway was built to withstand more than a few paltry grappling irons.

He peered cautiously over the steel-plated wall. More reinforcements were on their way. Horsemen mounted on jet-black steeds galloped to the head of the army of ogres and orcs. Glandallin instantly recognized the pointed ears of the tall, slim creatures.

A red glow shone from the horses' eyes and their hooves struck the ground in a shower of white sparks. Two riders thundered to the gateway and gave orders to the troops. The orcs and ogres set about clearing the pathway of fallen masonry so the assault could start afresh.

Wheeling round on their horses, the riders found safe quarter from which to watch. One of the two creatures unshouldered a mighty bow and nocked an arrow against the woven bowstring. The marksman's gloved fingers held the weapon loosely as he bided his time.

Hastily, the fifthlings pushed boulders over the parapet and onto the beasts below. The enemy flinched, jostling to evade the projectiles, and three of the orcs turned to flee. The archer raised his bow. Before the deserters could take flight, the first arrow, too fast for Glandallin to follow, sang through the air and an orc fell to its knees.

Already a second missile, uncommonly long for an arrow, sped from the archer's bow. The second beast perished, shrieking, followed a moment later by the third. The remaining minions took heed of the warning and resumed their work on the pathway. The orcs did not venture a protest at the murder of their kinsmen.

By the coming of dawn, the path had been cleared.

The fifthlings marveled at the scene unfolding before their eyes. The sky had brightened in the east, heralding the rising of the sun, yet a thick bank of fog loomed in the north. Its luminous center, a maelstrom of black, red, and silver, flickered with coursing light.

In defiance of the wind, it rolled toward the gateway, sweeping over the beasts below. The raucous orcs fell silent, huddling nervously together and shrinking away from the fog. Stooping, the ogres allowed it to pass. As if hailing their leader, the riders bowed their heads and saluted the vaporous mass. The shimmering mist lowered itself gently to the ground and hovered in front of the horses.

Then the unthinkable happened. With a shudder, the first of five bolts on the doors shot from its cylinder. The gateway quaked. Someone had spoken the incantation, delivering Girdlegard into the clutches of the invading hordes.

"No!" bellowed Glandallin, turning his back to the enemy and leaning over the inner wall to seek the culprit below. "No dwarf would ever…"

Glamdolin Strongarm. Alone, the dwarf was standing by the doors, lips moving, hands raised in supplication.

"Silence!" Glandallin bellowed. "Can't you see what you're doing?"

His shouts fell on deaf ears. The second lock glowed brightly, illuminated by the runes. The bolt creaked back.

"He's been bewitched," muttered Glandallin. "The fog has infected his mind." The third bolt left its ferrule and shot free.

At last the custodians of the gateway stirred. Springing to their feet, they darted down the staircase, racing to put a stop to the treacherous magic before it was too late. The fourth bolt drew back. With one bolt remaining, Glamdolin was still standing unchallenged on the pathway.

Time is against us, Glandallin thought grimly. "Forgive me, Vraccas, but I have no choice." He gripped his ax and hurled it with all his might and fury at his comrade-in-arms.

The blade sliced through the air, spinning, then plunged sharply toward the ground. Glandallin's aim was unerring and the ax drove home.

Glamdolin groaned as the weapon struck his shoulder. Blood spraying from the wound, he stumbled to the ground. Watching from above, Glandallin sent a quick thanks to Vraccas for guiding his blade.

His relief was short-lived. Death had come too late to prevent the traitor from achieving his terrible purpose. The final bolt shot back.

Slowly, the colossal gateway opened. The vast slabs scraped and dragged across the ground, as though reluctant to obey the treacherous command.

There was a grinding noise of stone on stone. The chink became a narrow channel, which widened to fill the breadth of the path. Time slowed to a crawl as the gates swung open. One final creak and for the first time in creation the path into Girdlegard was clear.

No! Glandallin stirred from his paralysis and hurtled down the steps to join Giselbert and the remaining warriors defending the gates.

He was the last but one to take his place in the doorway. Already the others had closed ranks and were holding their shields in front of their bodies, their axes held aloft.

Shoulder to shoulder they formed a low wall of flesh against the tide of orcs, ogres, trolls, and riders. Forty against forty thousand.

The enemy hung back, fearing an ambush. Never before had the gates opened to allow their passage.

Glandallin's gaze swept the front line of monstrous beasts, shifting back to survey the second, third, fourth, fifth, and countless other grunting rows, all poised for the attack. He glowered from under his bushy eyebrows, forehead furrowing into a frown.

Giselbert lost no time in reversing the incantation. At the sound of his voice, the gates submitted to his authority, swinging back across the pathway but moving too slowly to stop the breach. Giselbert strode behind his troops, laying a hand on each shoulder. The gesture was a source of solace as well as strength, calming and rallying the last defenders of the gates.

Trumpets blaring, the riders ordered the attack. The orcs and ogres brandished their weapons, shouting to drown out their fear, and the army advanced with thundering steps.

"The path is narrow. Meet them line by line and give them a taste of our steel!" Glandallin called to his kinsfolk. "Vraccas is with us! We are the children of the Smith!"
